74250945 divided by 64 
We want to figure out the number of times 74250945 can be divided by 64.

Moving on to step 1:
When dividing 7 by 64, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 64

On to step 2:
64 can be fit into 74 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 64 from 74 to get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 64

On to step 3:
When dividing 102 by 64, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 64 from 102, we get 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 64

Let's proceed to step 4:
The number 64 fits into 385 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Deduct 384 from 385 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 64

Step 5:
The number 64 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 1160.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 64

Moving on to step 6:
When dividing 109 by 64, we get 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 11601.0
If we take 64 away from 109, we end up with 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 64

On to step 7:
The number 64 fits into 454 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 116017.0
The remainder is 6 after subtracting 448 from 454.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 64

Going ahead to step 8:
When dividing 65 by 64, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1160171.0
Deduct 64 from 65 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
64 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1160171.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
64 goes into 100 1 times with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1160171.01
Deduct 64 from 100 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
360 divided by 64 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 1160171.015
Deduct 320 from 360 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 64, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 1160171.0156
Deduct 384 from 400 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
64 can be fit into 160 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 1160171.01562
If we subtract 128 from 160, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1160171.015625
Deduct 320 from 320 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 15:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1160171.015625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 16:
64 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1160171.015625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1160171.015625 and a remainder of 0.0.
